Hex for this Drawing ?
Does anyone have the hex for this driver ? Or could point me in the direction of where this drawing came from.

If you want to use the SAA1057 instead of the Motorola unobtainium chip, I can put up a little programme that generates the hex for your frequency of choice. You just write it into the 12F509, and away it does - a neat little fixed frequency PLL.

I disagree - There are plenty of ‘145170s on AliExpress for pennies. They might be copies but they work fine.
In my opinion it’s a better choice than the SAA1057 because you get a reliable lock detect.

If you want stable and accurate lock detect, you want to use the LMx2306 series.
I'd be interested in the 145170 for pennies - send me a link!

I bought around 100 of the 145170’s from AliExpress also. They were all smt devices and the seller dumped them into a bag, rather than supplying on tape - I couldn’t send them off to the pick and place assembly because of that, and ended up using the lmx2541 instead.
